Django channels AsyncComsumer cannot catch the custome Exception
I'm building a chat app with Django-channels. I use AsyncConsumer. In my consumer, I have method chatroom() that tries to call another method _can_access_room(). In _can_access_room() there's a case it raises a custom Exception (inherit from Exception). But I cannot catch the custom Exception in chatroom(). The log shows that it raised, but WebSocket disconnects. I set a breakpoint on the line that catches the exception but it doesn't stop there. But if I catch the base Exception, it works. Please help, thanks ^^ Here's my code: async def chatroom(self, data: dict): # check room in group or not? if group_from_room_id(data.get('room_id')) in self.groups: await self.chatroom_send(data) else: try: a = await self._can_access_room(data) except CustomException as e: print('ahihi') @database_sync_to_async def _can_access_room(self, room_data: dict): room_id = room_data.get('room_id') chat_room: ChatRoom = ChatRoom.objects.filter(id=room_id).first() if not chat_room: raise custom_exceptions.RoomDoesNotExist Here's log: ... , line 455, in thread_handler return func(*args, **kwargs) File "***********/consumers/chat_room_consumer.py", line 153, in _can_access_room raise custom_exceptions.RoomDoesNotExist common.custom_exceptions.RoomDoesNotExist WebSocket DISCONNECT /ws/chat/winners [127.0.0.1:49452] -
How to build a Django QuerySet to check conditions on two manyToMany fields
I have the following models (simplified): class Resource(models.Model): name = models.CharField(max_length=64, unique=True) class ResourceFlow(models.Model): resource = models.ForeignKey(Resource, related_name="flow") amount = models.IntegerField() class Workflow(models.Model): inputs = models.ManyToManyField(ResourceFlow, related_name="workflow") class Stock(models): resource = models.ForeignKey(Resource, related_name="stock") amount = models.IntegerField() class Producer(models.Model): workflow = models.ForeignKey(Workflow, related_name="location") stocks = models.ManyToManyField(Stock, related_name="location") I would like to test with computation done by the the DB engine if I can start a production. A production can start if I have enough stock: for my Producer's workflow, all inputs ResourcesFlow amount have to be present in the Producer'stocks So the queryset might be one those result: for a given producer return all stocked resources that do not fulfill Workflow inputs amounts conditions for a given producer return inputs resources needed for the workflow that are not in sufficient quantity in its stocks It is possible to do that in Django? -
django server log is full of "NoneType: None" messages
The log of my REST Server app is full of messages saying NoneType: None Is there a way to know where these messages are generated?.

Would this make my code faster? Should I not follow Django's structure best practices and would that affect my website's security?
I don't know what makes my code fast or slow... is it the quantity of lines? How separated between different files it is? What I am trying to do? On a Django website could my website security be compromised because of me not following Django's project structure best practices? (if that would give my code more speed) How could I make my Django website as fast as possible without compromising security? -
How to implement new log_action for LogEntry in admin views
I'm trying to display every actions performed on my models on an admin page, using LogEntry. So far I see actions done through the admin (which is the way LogEntry works by default if I understood well), but I would like to catch actions performed through my VueJS frontend as well. Not sure how to do this properly ! This is my code in admin.py (django 4.0) from django.contrib import admin from .models import * from django.contrib.admin.models import LogEntry, ADDITION, CHANGE class MoniterLog(admin.ModelAdmin): list_display = ('action_time','user','content_type','object_repr','change_message','action_flag') list_filter = ['action_time','user','content_type'] ordering = ('-action_time',) admin.site.register(LogEntry,MoniterLog) -

Issue Installing ODBC Driver 17 for SQL Server for Linux
My end goal is to use Azure SQL Edge (ASQLE) instead of Microsoft SQL Server in a Docker container for a local development instance of an application (since MSSQL doesn't run on ARM). The container running ASQLE seems to be fine, but when I try to start my application I get the following error from the container running the API (which is powered by Django): django.db.utils.Error: ('01000', "[01000] [unixODBC][Driver Manager]Can't open lib 'ODBC Driver 17 for SQL Server' : file not found (0) (SQLDriverConnect)") I have seen this issue a few other times on the web (1, 2) and they all seem to start with ensuring the driver installation, which is what I am having problems with. Following the guide provided by Microsoft, I run the following four commands (on a fresh ASQLE image) and get these outputs: root@7c38f5ceb89c:/$ curl https://packages.microsoft.com/keys/microsoft.asc | apt-key add - % Total % Received % Xferd Average Speed Time Time Time Current Dload Upload Total Spent Left Speed 0 0 0 0 0 0 0 0 --:--:-- --:--:-- --:--:-- 0Warning: apt-key is deprecated.

Cloudinary upload image from Django admin panel from two or more databases
everyone. I decide to use Cloudinary for storing images. This is my model field with image: avatar = models.ImageField(upload_to='avatar/', default='avatar/default.png', blank=True) All works fine for me, but I have one little issue. When I uploaded the image from admin panel, cloudinary upload it to my cloudinary folder 'avatar' with some modified name, for example: 'july2022_kda4th' or 'july2022_aidkdk' But when I uploaded this image from admin panel of another database (production), cloudinary upload the image with another name. So, I have two similar images in cloudinary. It's not convenient. How can I fix it? -

How to enable basic http auth through Django?
How do you enable basic http auth in Django? According to the Django docs, basic http auth can be enabled directly in Django, requiring no server support. I've added django.contrib.auth.middleware.RemoteUserMiddleware to my MIDDLEWARE list and added django.contrib.auth.backends.RemoteUserBackend to my AUTHENTICATION_BACKENDS list. so I created a simple view: import logging from django.http.response import JsonResponse from django.views.decorators.csrf import csrf_exempt @csrf_exempt def test_auth(request): print('Request.user: %s' % request.user) print('META:', request.META) print('REMOTE_USER:', request.META.get('REMOTE_USER')) if request.user.is_anonymous: return JsonResponse({"success": False}, safe=False) return JsonResponse({"success": True}, safe=False) and registered it in my urls.py as /test_auth. And then to test, I call it using curl: curl -u "myuser:mysupersecretpassword" -0 -v -X GET http://127.0.0.1:8000/test_auth However, it shows that Request.user: AnonymousUser, implying the RemoteUserBackend is not being called. I've tested my myuser:mysupersecretpassword credentials, and confirmed I can login as that user via the normal Django admin login. I'm using Django 3.2. Why isn't basic auth working with RemoteUserBackend? Is there another step that I'm missing? -
Django: permission required based on roles, but using a single User model
I have a custom user model that looks like this: class SpotUser(AbstractBaseUser): BASIC = 1 ADMIN = 2 QA = 3 RESEARCH = 4 uid = models.IntegerField(primary_key=True) name = models.TextField(blank=True, null=True) email = models.EmailField(unique=True) password = models.TextField(blank=True, null=True) USER_TYPE_CHOICES = ( (BASIC, 'Basic'), (QA, 'Qa'), (RESEARCH, 'Research'), (ADMIN, 'Admin') ) user_type = models.TextField(choices=USER_TYPE_CHOICES, default=BASIC) last_login = models.DateField() USERNAME_FIELD = 'email' REQUIRED_FIELDS = [] class Meta: managed = False db_table = 'users' I would like to add permissions based on the role. For example: Admin and research can update users via backend API, but QA and Basic cannot. Is it possible to implement this feature without using multiple User models? -
